TPI8011N

TPI Tripolar protection for ISDN interfaces Features ■ Bidirectional triple crowbar protection ■ Peak pulse current: IPP = 30 A , 10/1000 µs ■ Breakdown voltage: – TPI80N: 80 V – TPI120N: 120 V ■ Available in SO-8 package ■ Low dynamic breakover voltage: – TPI8011N: 120 V – TPI12011N: 170 V Benefits ■ Low capacitance from lines to ground, allowing high speed transmission without signal attenuation ■ Good capacitance balance between lines to ensure longitudinal balance ■ Fixed breakdown voltage in both common and differential modes ■ The same surge current capability in both common and differential modes ■ A particular attention has been given to the internal wire bonding. The “4-point” configuration ensures a reliable protection, eliminating overvoltages introduced by the parasitic inductances of the wiring (LdI/dt), especially for very fast transient overvoltages SO-8 Complies with following standards ■ CCITT K17-K20 – 10/700 µs, 1.5 kV – 5/3...
